ble fastener, such as the socket member of a 5 snap-fastener, in whichthe separable fastener member is so constructed as to present the leastpossible projection and thereby minimize the bulging of the fastenedparts.

The invention in its limited aspect, consists of a slide of conventional'or approved form adapted to be adjusted upon a strap or belt andfrictionally or otherwise heldin adjusted position thereon, and providedwith a resilient socket composed of 'an eyelet-like member which is openat both ends, one end of which is reduced and clinched to and upon theslide and its other end supplied with an open ring spring, adapted toengage a stud or head 20 so as to fasten together the parts upon whichthe slide fastener-and the stud are respectively mounted, as I willproceed now more particularly to explain and iinally claim.

In the accompanying drawingl illustrating the invention, in the severalfigures of which like parts are similarly designated, Figure l is a topplan view and Fig. 2 is a bottom plan view of a slidehaving a ringspring socket secured in position thereon by a reduced and solid endrolled over upon the slide. Fig. 3 is a section illustrating theapplication of the slide of Figs. l and 2, to a strap or belt. Fig. 4 isa sectional elevation illustrating a .suitably mounted stud or head inposition to 5 lbe engaged with the socket of the slide. Fig.

5Y is a top plan view; Fig. 6 is a bottom plan view, and Fig. 7 is across section of a slide fastener in which the socketv element has'itsupperreduced end cut, slit, kerfed or otherwise partly severed so as toJfacilitate the attachment of the sockel element tothe slide by beingrolled over the same. Fig. 8 is a section of the blank of theeyelet-like member of the socket, and Fig. 9 is a cross-section of thefinished socket member ready to be ap-y plied to the slide.

The figures of the drawing are obviously enlarged.

The slide l, may be of metal and ofany shape, size or configuration tosuit the use for which designed. As shown in the drawstated.

ing, the slide is designed for a strap and has two parallel straightsides with curved ends. Near each end is a transverse slot 2 and betweenthese slots is a central opening 3. The part l is curved longitudinallyto adapt it to the use to which applied. In any case, the slide may beofrelatively thin material. The slots 2 are adapted to receive a strap 4Lor other article to which itis applied, as indicated in Fig. 3 and isthe sole strap engaging member and outside finish.

In the opening 3 is mounted the vfastening element, same being, asherein shown, an eye# letlike member 5, open at bothends, the lowerportion of which is beaded to receive and sup-- port a ring spring 6.The upper end of this eyelet-like device is reduced and may be leftsolid as lshown in Figs.1,2l and 3, and this end is passed through theopening 3 until the slide rests upon the shoulder 7 L of the ring springsupporting bead andthen the portion of the eyelet-like device whichpasses through the opening in the slide is rolled over on top of theslide into intimate contact with the ytopwhereby the fastening device isfirmly mounted upon the slide, and with very little and scarcely anyappreciable extension above the level of the' outer surface of theslide, thereby ensuring a very fiat and symmetrical slide fastener.

As shown in Figs. 5 to Y9 inclusive, the reduced portion of theeyelet-like fastener element that extends beyond the upper surface ofthek slide may be cut, slit, kerfed or otherwise partly severed, as at8, so as to spread when this edge is rolled down over the upper surfaceof the slide tosecurethe ,fastening device in position.

In the unslitted eyelet-like member of Figs. l1, 2 and 3, as Well as inthe slittedform shown in Figs. 5,6, 7, 8 and 9, the-shoulder 7 servesthe double purpose of locating the spring in its bead and theeyelet-like member in the slide. In both assemblies as shownjres'pecltively in Figs.;1 to 3. and Figs. 5 to 9, they shoulder 7 on the beadedend of the eyelet comes into face to face Contact with the slide memberVfor-the double purposevlast above Kee feo

fect the union of the two snap-fastener elements'.

Y v In Fig. l the stud member of the snap fastener device is shown asmounted upon -a piece of fabric or other material represented at 16.

It will be noticed that the described slide fastener is characterized byeXtreme tlatness, and that the stud in entering the socket has atendency to protrude through the slide and this admits of the slid-ebeing made much thin# ner than the conventional types, especially thoseto which the socket is secured by means of av separate flanged eyelet.

Variations in details of construction are permissible withintheprinciple of the invention and the claims following.

What I claim is 1. A slide fastener, comprising a single Vtransverselyslotted slide member of relative thinness, and having a central openingthrough which the aftermentionedY fastener Vsocket is applied thereto,and a-socket comprising an open-,ended eyel-et-like part with one endreduced and passed through vsaid central openingand rolled down on topof the slide member and the other end beaded and a ring springyieldingly supported in said beaded end, said beaded end having ashoulder which shoulder comes into face to face Contact with the slideelement and serves to locate the relation of the socket to the slide andthe spring to the beaded end.

2. A slide fastener, comprising a single transversely slotted slidemember of relative thinness, and having a central opening through whichthe aftermentioned fastener socket is applied thereto, and a socketcomprising an open-ended eyelet-like part with `one end reduced and slitat numerous points and passed through said central opening-and rolleddown on top of the slide member, and

the other end beaded and a ring spring yieldingly supported in saidbeaded end, said beaded end having a shoulder which shoulder Vcomes intoface to face contact with the slide y element and serves to locate'therelation of prising an open-ended eyelet-like part with one end reducedand passed through said central opening and rolled down on top of theslide member and the other end beaded,

a shoulder formed on the beaded end, and a ring spring yieldinglymounted in said beaded end, the said shoulder coming into face to facecontact with the slide member and serving to fix the location of thesocket mem-v ber' on the slide and the spring in the beadery of theaperture, the remainder of fsaid retainer -being bent first outwardly ofthe edgeA ofthe aperture into engagement with the other face of theslide member and then inwardly linto substantially semi-circularcross-section, and thereby forming a groove of substantially thethickness of the slide member to receive the peripheral portion of theslide member surrounding the aperture and to maintain the retainerpermanently in position on theslide member against displacementtherefrom, said semi-circular bent portion having an aperture in the endthereof arranged co-aXially ofthe aperture in the slide Vmember for thepassage Vof a stud, and a resiliyent ring arranged in the semi-circularportion, and adapted to expand therein to permit the passage ofastud'therepast, and to contract lto removablyrmaintain the stud in thesocket afteritspassage through the aperture.
